This lightBox has the following features. You can test it by modifying the code ^-^:

The screen can be completely masked by clicking any position on the page (at this time, it is impossible to directly control any elements including the scroll bar ), the select element can be masked without hiding in IE6 (iframe masking: After masking, if you drag the scroll bar, select will still be moved to the top layer ).
LightBox highly adapts its content and presents a perfect center state.
When the content is a single row, it is displayed in the center; when the content is multiple rows, it is displayed in the left; The content height makes the scroll bar appear when the lightBox exceeds the screen, and displays it in the top, so that readers can fully read it.
If you are interested, you can refer to the following tips for creating this lightBox:

1. Full Screen masking:

A. Hide the html/body scroll bar.
B. Use a div as a mask and a div as a page with a scroll bar.
